GEORGE VOLL, OF CINCINNATI, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THEIRELAND MANUFACTURING COMPANY, OF SAME PLACE.

FACE-PLATE FOR LOCKS.

SPECIFICATION forming part of Letters Patent No. 333,434, dated December29, 1885.

Application filed May 16, 1885.

To all whom it may concern.-

Be it known that I, GEORGE VOLL, of Cincinnati, Hamilton county, Ohio,have invented a new and useful Improvement in Face- 5 Plates for Locks,of which the following is a specification.

The invention is designed to enable those mortise-locks such as areusedin folding doors to be applicable at will to either a right or a IOleft hand door, thus obviating the great expense now incurred in makingevery such lock for use on either a right-hand or a lefthand doorexclusively. This purpose I accomplish by the construction of adetachable and r r5 versible faceplate, substantially as hereinafterfully explained.

In theaccompanying drawings, Figures 1 and 2 are perspective viewsshowing my lock adapted to a right-hand and to a left-hand 2c door,respectively. Figs. 3 and 4 are top Views of the same. Fig. 5 is a rearview of a reversible face-plate, illustrating my invention. Fig. 6 is aface view of the keeper.

A and B may represent the meeting por- 25 tions of two folding doorshaving the customary beveled surfaces a b and rabbets a b.

C is a beveled and rabbeted keeper attached in the usual manner to thebeveled rabbeted edge of one of the doors A. the beveled suro face ofthe keeper being shown at c.

D may represent'a mortise-lock.

E represents a spring-latch thereof, which is, for use with myimprovement, made capable of reversal in any one of the familiar ways 5of reversing lock-latches.

F represents the lock-bolt, whose head f is identical in cross-sectionwith the cross-section of the head 6 of spring-latch E, and whoselocation is as much below the median line of 40 the look as that of thespring-latch is above it.

The face-plate G has the customary bevelg and rabbetg and twoprecisely-similar Openings. g g, for the heads 6 and f of the latch andbolt, respectively, said openings being lo- 45 cated in such positionsrelatively to the other parts of the plate that, no matter which edge ofthe plate is placed uppermost, one of them will register with the headof the latch and the Serial No. 165,722. (MotleL) other with the head ofthe bolt. By this means the face-plate is made reversible. The rabbetsof the faceplate and keeper are of course complementary to each other,and the openings in both correspond.

The various beveled surfaces are in practice, and likewise in theaccompanying drawings, so slight as to be scarcely perceptible at firstglance; but on careful examination they will be found to be fullyillustrated.

Projecting rearwardly from the face-plate G are two lugs, H H, whoseperforations h h receive the screws J J, by which the said face-plate issecured to the lock-case either for a right-hand or a left-handarrangement at will of the user. The two halves of the said face-platefrom its mid-length outward being identical in every respect, includingthe orifices for the latch and bolt heads, respectively, which latterhave, as already mentioned, an identical crosssection, it becomespossible, after detaching the face-plate, to apply it in the invertedposition shown in the figures. The latch E, having previously to suchreattachment ofthe face-plate, been reversed in the usual way ofreversible locks and made to occupy the orifice in the keeper previously00- 7 cupied by the bolt, and vice versa, the lock is converted from aright-hand to a lefthand one or from a left-hand to a right-hand one asthe case may be.

My invention is manifestly applicable to any customary form of beveledface-plate of mortise-locks, whether rabbeted or otherwise.

I claim as new and of my invention The combination, with a reversiblekeeper having openings correspondingto those of the face-plate and arabbet complementary to that of said plate, of the mortise door-lockhaving the lock-bolt, the reversible latch, and the reversible rabbet-edface-plate, as set forth.

In testimony of which invention I hereunto set my hand.

GEORGE VOLL.
